java public field when inherit

Question

Assume there are two classes:

class A{
    public int a=0;
}
class B extents A{
    public int a=1;
}

I've tried this code:

A a=new B();
B a1=new B();

and a.a is 0, a1.a is 1.

Is there any method to access a1's super.a?

Define a method in B to return it – OneCricketeer Sep 10 '16 at 16:32 — OneCricketeer, Sep 10 '16 at 16:32
You could always do `((A) a1).a`. – Louis Wasserman Sep 11 '16 at 17:19 — Louis Wasserman, Sep 11 '16 at 17:19

Create a method in class B to fetch the value of superclass variable a through super.a

class A {  
    public int a=0;
}  

class B extends A {  
    public int a=1;

    public int superClassA() { 
        return super.a; 
    } 
}

Use a1.superClassA() to fetch the value for a from class A

It seems that we must use a function to get the value,isn't it right? – keai4le Sep 10 '16 at 18:33
Yes because Java doesn't allow variable overriding. – arif abbas Sep 11 '16 at 03:47
